public class Element extends Object
The base class for elements of the content of a page. An element is a building block; everything in a PDF file is an element. An element object can be associated with a large amount of unmanaged memory in APDFL and should be deleted when the object is no longer in use.

  • Method Details

    • delete

      public void delete()

    • getMatrix

      public Matrix getMatrix()
      The transformation matrix for the element.

    • setMatrix

      public void setMatrix(Matrix matrix)
      Set the transformation matrix for the element.
      Parameters:
      matrix - the transformation matrix for the element.

    • translate

      public void translate(double tx, double ty)
      Translate an element by (tx,ty) units using the matrix [ 1 0 0 1 tx ty ].

    • rotate

      public void rotate(double theta)
      Rotate an element by T degrees counterclockwise units using the matrix [ cos T sin T -sin T cos T 0 0 ].

    • scale

      public void scale(double sx, double sy)
      Scale an element by (sx,sy) units using the matrix [ sx 0 0 sy 0 0 ].

    • setClip

      public void setClip(Clip clip)
      Sets the current Clip for an Element.

      Parameters:
      clip - The clip to set as the current clip for this element.

    • getClip

      public Clip getClip()
      Gets the current Clip for an Element.

      Returns:
      - The current Clip for this Element.

    • clone

      public Element clone()
      Makes a copy of the element.

      Make a copy of an element to obtain a new element that has a distinct set of attributes.

      Note: TextRun objects may not be cloned.

      Returns:
      The copied element.

    • clone

      public Element clone(EnumSet<ElementCloneFlags> cloneFlags)
      Makes a copy of the element.

      Make a copy of an element to obtain a new element that has a distinct set of attributes.

      Note: TextRun objects may not be cloned.

      Parameters:
      cloneFlags - Flags that modify the cloning operation.
      Returns:
      The copied element.

    • getBoundingBox

      public Rect getBoundingBox()
      The bounding box for this element.

      The bounding box is a rectangle that is guaranteed to encompass the element, but it is not guaranteed to be the smallest box that could contain the element. For example, if the element is a Path that contains an arc, the bounding box encompasses the bezier control points, and not just the curve itself.

      Returns:
      The bounding box for this element. The coordinates of the bounding box are specified in user space coordinates, relative to the element's Content. Note that user space coordinates correspond to unrotated pages; any rotation specified in the page dictionary is not taken into account.
